White dots as numbers and script is blank

Hello. I am a small game developer and I been working on a project for these past few weeks up until yesterday when I woke up to this screen:

My script is empty with a bunch of white numbers on the side. Although the script looks empty, it still retains its contents because when I hover over it, it says it’s not 0 kb:

If anyone knows the solution or if this is just simply a newbie issue, please let me know. I would greatly appreciate it. =)
